TRAVELING-FLAT CARDlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 451,367, dated April28, 1891.

Application filed July 31, 1890.

T0 00% whom it may concern.-

Be it known that I, WILLIAM P. CANNING, a citizen of the United States,residing at Lowell, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement inTraveling-Flat Oarding-Engines, of which the followingis aspecification.

My invention relates to traveling-flat carding-engines, and isapplicable to carding-engines in which there is a lateral openingbetween any part or all of the flexible bend and the main bend, throughwhich air, flyings, or any substance can pass from side to side of thebends. It is especially applicable to any carding-engine in which theinner faces of the flexible and the main bends are in the same planeorsubstantiallyin the same plane.

The object of my improvement is to prevent the passage of air, flyings,or substances of any kind through such an opening and to steady theflexible bend in position. To this end I close any such opening betweenthe flexible and the main bends by a coveringplate mounted upon the mainbend on the side thereof opposite to the brackets which support theflexible bend.

Figure 1 of the annexed drawings is a partial side view ofacarding-engine to which my improvement is applied. Figs. 2, 3,and etarepartial sections of different modifications of the same, taken at theline S Sof Fig. 1. Fig. 2 represents the application of thecoveringplate in a case when the flexible bend is over the main bendwith theinner faces of the two bends in the same plane or substantiallyin the same plane. In Figs. 3 and 4 the flexible bend is representedwith arabbet or recess in its interior face, whilein Fig. 2 no suchrabbct appears. In Fig. at the covering-plate is represented as being anintegral part of the main bend and as being proportionately thicker thanit is represented to be in Figs. 2 and 3. Fig. 5 is a section of theflexible and main bends and covering-plate through one of thesupporting-brackets. Fig. 6 is a view similar to Fig. 1, but showing theconnection between the flexible bend and the supporting slides orbrackets therefor, indicating the chain of traveling flats by dottedlines, and showing Serial No. 360,586. (No model.)

various rollers and supporting-brackets employed in connection with saidchain.

In the figures, Frepresents the frame of the carding-engine; B, the mainbend; Z), the flexible bend; O, the main cylinder; O, the shaft of themain cylinder; a, the coveringplate; a the space between the flexibleand the main bends, through which substances could pass from side toside of the bends were it not for the covering-plate a.

s 8, Figs. 1, 2, 3, 5, and 6,arescrews orother fastenings, by the aid ofwhich the coverin plate a is attached to the main bend. h

P P P P are protectors for the edges of the wire clothing upon the maincylinder or upon the flats.

f designates the flats, and p pp the brackets which support the studsthat carry the flexible bend.

In Figs. 1 and 6 the covering-plate a a is represented by dottedcircular arcs; but its outline might have a different shape from thatrepresented in said figures. The plate will serve its purpose as acovering-plate if it shall be everywhere sufficiently wide tosubstantially prevent the passage of substances of any kind through thespace a a from side to side of the bends in any position of adjustmentof the flexible bend.

In Figs. 2 and 3, a is represented as a somewhat thin covering-plate,preferably of steel, which is of sufficient width to overlap a portionof the main bend, a portion of the flexible bend, andthe space betweenthem. A It prevents the passage of substances of any kind through thespace a 003.

In Fig. 3 both the flexible bend b and the main bend B are rabbeted ontheir inner faces. Generally I prefer to make the depth of the rabbet inthe flexible bend and the depth of the rabbct in the main bendsubstantially equal to the thickness of the plate a, a, so that theinner faces of these three parts shall be in the same plane.

In Fig. 2 no rabbet is represented either in the flexible or in the mainbend; but the 9 inner faces of both of those pieces are in the sameplane with the outer face of the covering-plate ct.

In Fig. i the plate a is represented as being an integral part of themain bend, and as being proportionately thicker than it is representedto be in Figs? and The plate a, when formed as a separate plate, may beattached to the main bend B by bolts, screws, rivets, or otherfastenings. I11 Figs. 1, 2, and 3 countersink-headed screws arerepresented as put through the plate a from the inside and screwed intothe main bend. I prefer to attach the plate to the main bend by the aidof such screws. Whenever the plate a is used, the flexible bend b isbounded, confined, and steadied in position between the plate a on theinside and the brackets or their accessories, which support the studsthat carry the flexible bend, on the outside; and this is a distinctimprovement. A part of one such bracket 11 is represented in Fig. 5 withthe flexible bend 1) between it and the plate a.

In Fig. 6 I have shown supporting and adjusting slides p p p of a kindin common use. These slides are slotted, as at p, to permit ofadjustment, and are secured in place by bolts and nuts 11 One of. theseslides namely, that lettered pis represented as carrying a pin or stud.9, which is secured to it in a fixed position by one end, while theother end of the stud enters a circumferential slot 2f in the flexiblebend. Another of these slides 19 is represented as carrying a stud s,which is secured to it in a fixed position by one end, while the otherend of the stud enters a round hole in the flexible bend. The thirdslide or bracket p is represented as having a slot t into which the pin5 enters, the pin being secured to the flexible bend in afixed position.In connecting either end of the flexible bend with its adjacentadjusting and supporting slide or bracket the slot may be in the bracketor the pin may be secured to the latter, as maybe preferred. The screwsq qg if turned one way orthe other, cause the slides or brackets to movetoward or away from the axis of the main cylinder. The slides orbrackets lettered r and r are those which in practice support thegrinding-roller and the roller by which the chains carrying the flatsare tightencd.

In Figs. 2 and tare shown well-known forms of protectors for the edgesof the workingsurfaces of the card-clothing upon the main cylinder andupon the flats. One of these protectors P consists of an angle-plateplaced upon the leather or other backing of the cardclothing of each ofthe flats and screwed or riveted in place, one portion thereof standingin a vertical plane parallel with the teeth upon the said card-clothing. Another proteeter P consists of a ring or plates secured by screws tothe end of the cylinder 0 and projecting at the side of the teeth on thecylinder to or near the points thereof. The protector P consists of ashort piece of iron or steel wire of rectangularsection. The leather orother backing of the card-clothing of the flat is extended outwardbeyond the teeth of the said clothing between the wide face of the flatand the protector P, and the ends of the protectorP are bent around theedges 01": the flat and compressed into narrow grooves, which runlengthwise of the flat near to the edges of the wide flange to which theclothing is fastened. The protector P consists of a ring or platesscrewed to the end of the cylinder and extending alongside of andparallel with the teeth on the cylinder and flats. Any other good termsof protector may be substituted. I do not claim the invention of theprotectors herein described.

Although I have herein shown the flexible bend placed in substantiallythe same vertical plane with the main web of the main bend and the mainbend notched or recessed atits outer edge, with the flexible bendlocated in the notch or recess, I do not herein lay claim to thisfeature per se, inasmuch as it is claimed in an application filed oneven date herewith by Ohanning \Vhitaker, oi Tyngsborough,Massachusetts, and myself as joint inventors, and bearing the serialnumber 360,588.

I claim 1. The combination, with the flexible bend and the main bend, ofthe brackets carried by the main bend and supporting the flexible bend,and the covering-plate on the opposite side of the main bend from thebrackets, sub stantially as described. a

2. The combination, with the flexible bend, rabbeted as described, ofthe main bend and the eovering-plate thereon projecting over therabbeted portion of the flexible bend, substantially as described.

3. The combination, with the flexible bend and the main bend, bothrabbeted, as described, ot the covering-plate secured to the main bendand projecting over the rabbeted portion of the flexible bend,substantially as described.
